You have an assortment of ww2 buttons and medals, the medal bar is as followed (WW2 victory/service medal, US Defense medal, US Air force good conduct medal)

The National Defense and Air Force Good Conduct would both be post World War Two. The National Defense medal was introduced in 1953 and the Air Force Good Conduct was introduced in 1960.

In the first picture you have collar dogs. There are two aviation, one armor, one signals, one ordnance, one medical and one engineer. The one resembling a ships wheel I am not familiar with.

The third image looks like an enlisted man's cap device. Unsure of the era.

The WWI collar disk are basic US and U S National Army. The other pin is Army transport.

The last button looks like it could be Spanish American War 1898 IMO. Also the ribbons are Philippian liberation and Asiatic Pacific Campaign, each with one battle star.

Thanks
